Abstract
Titanium dioxide (TiO2) thin films were deposited on glass slide by Sol-gel method with dip coating technique for 1 and 10 layers. TiO2 films were annealed in air at temperature of 200 and 400 °C for studying the effects of annealing temperature on the optical property via simple spectrophotometric method. The result showed that the optical transmission of TiO2 films was increased after annealing. For TiO2 films dip coating 10 layers, the optical transmission showed interference peak of light wave. It was calculated for finding the optical constant of TiO2 films. The refractive index (n) of as-deposited TiO2 films was estimated as 2.19 and was found to increase with the annealing temperature at 200 and 400 °C as 2.33. The thickness was decreased from 367.68 to 353.74 and 341.17 nm with corresponding to the conditions as-deposited, annealed 200, and 400° C. Moreover, the band gap energy (Eg) was decreased from 3.52 to 3.47 and 3.42 eV.
